Last year at the ECDL 2004 conference, we reported some initial progress and experiences developing DSpace as an open source community-driven project [8], particularly as seen from an institutional manager’s viewpoint. We also described some challenges and issues. This paper describes the progress in addressing some of those issues, and developments in the DSpace open source community. We go into detail about the processes and infrastructure we have developed around the DSpace code base, in the hope that this will be useful to other projects and organisations exploring the possibilities of becoming involved in or transitioning to open source development of digital library software. Some new challenges the DSpace community faces, particularly in the area of addressing required system architecture changes, are introduced. We also describe some exciting new possibilities that open source development brings to our community.

As more and more output from research institutions is born digital, a means for capturing and preserving the results of this investment is required. To begin to understand and address the problems surrounding this task, Hewlett-Packard Laboratories collaborated with MIT Libraries over two years to develop DSpace, an open source institutional repository software system. This paper describes DSpace in the context of the Open Archival Information System (OAIS) reference model. Particular attention is given to the preservation aspects of DSpace, and the current status of the DSpace system with respect to addressing these aspects. The reasons for various design decisions and trade-offs that were necessary to develop the system in a timely manner are given, and directions for future development are explored. While DSpace is not yet a complete solution to the problem of preserving digital research output, it is a production-capable system, represents a significant step forward, and is an excellent platform for future research and development.

Orientador: Victor Orlando Gamarra Rosado / Banca: Mauro Pedro Peres / Banca: Sebastião Cícero Pinheiro Gomes / Resumo: Biomodelagem é um termo genérico que designa a habilidade de replicar a morfologia de uma estrutura biológica em um modelo físico. Por ser uma técnica relativamente nova, sua disseminação é limitada pelo alto custo de aquisição de softwares proprietários e hardware de alto desempenho, impedindo sua utilização em hospitais públicos, centros de saúde e consultórios médicos. O objetivo principal desse trabalho é apresentar uma proposta de biomodelagem virtual através do uso de softwares livres instalados em equipamentos convencionais de informática e contribuir de forma efetiva para redução dos custos da técnica. Para atingir o objetivo, foi necessário identificar softwares livres dedicados e CAD que pudessem ser aplicados em conjunto para desenvolvimento de projetos em biomodelagem. Dentre a diversidade de programas disponíveis, observou-se que os softwares Invesalius 3.0 e FreeCAD 0.11 possuíam as características necessárias para aplicação da técnica. Baseado nos conceitos de biomodelagem, três estudos de caso foram abordados para elaboração do diagnóstico e planejamento cirúrgico, auxiliando o médico na tomada de decisões. Os resultados demonstraram que a biomodelagem virtual por meio do uso dos softwares livres Invesalius 3.0 e FreeCAD 0.11, instalados em equipamentos convencionais de informática, é viável para uso na rotina médica em diversas situações de diagnóstico e planejamento cirúrgico. As principais vantagens apresentadas são a redução dos custos em biomodelagem e a possibilidade de disseminação da técnica, permitindo a inclusão de um maior número de pacientes submetidos às tecnologias 3D / Abstract: Biomodeling is a generic term for the ability to replicate the morphology of biological structure in a physical model. As it is a relatively new technique, its dissemination is limited by the high cost of purchase of proprietary software and high performance hardware, impeding their use in public hospitals, health centers and physician offices. The main objectives of this work are to propose a virtual biomodeling through the use of open source software installed in a conventional computer equipment and to effectively contribute in reducing the technique costs. In order to achieve the proposed objectives, it was necessary to identify dedicated open source software and CAD open source software that could be applied together to develop biomodeling projects. Among the variety of programs available, it was noted that the software InVesalius 3.0 and the FreeCAD 0.11 had the necessary characteristics for the application of the technique. Based on the concepts of biomodeling, three case studies were discussed for making the diagnosis and the surgical planning, assisting the physician in making decisions. The results showed that the virtual biomodeling through the use of the open source software called InVesalius 3.0 and FreeCAD 0.11, installed in conventional computer equipment, is feasible for the routine use in many situations of medical diagnostic and surgical planning. The main advantages are the cost reduction in biomodeling and the possibility of spreading the technique, allowing the inclusion of a greater number of patients subjected to 3D technologies / Mestre

The proliferation of the Internet has amplified the use of social networking sites by creating a platform that encourages individuals to share information. As a result there is a wealth of information that is publically and easily accessible. This research explores whether open source intelligence (OSINT), which is freely available, could be used as a digital forensic investigative tool. A survey was created and sent to digital forensic investigators to establish whether they currently use OSINT when performing investigations. The survey results confirm that OSINT is being used by digital forensic investigators when performing investigations but there are currently no guidelines or frameworks available to support the use thereof. Additionally, the survey results showed a belief amongst those surveyed that evidence gleaned from OSINT sources is considered supplementary rather than evidentiary. The findings of this research led to the development of a framework that identifies and recommends key processes to follow when conducting OSINT investigations. The framework can assist digital forensic investigators to follow a structured and rigorous process, which may lead to the unanimous acceptance of information obtained via OSINT sources as evidentiary rather than supplementary in the near future.

The main Target is to compare commercial device for eye tracking analysis with a device made by DIY (Do it yourself) in the chosen environment. The work includes basic analysis methods Eye tracking. It offers a list of devices suitable for comparison, or marginally list of alternatives. A significant part of the thesis deals with construction of DIY tracker. The comparison is made on the basis of experimental measurements of commercial device and DIY device. The result is that in the selected conditions we can DIY device used because it is comparable with the commercial product. One of the sub-chapters is devoted also to question of the application DIY. In the last part was used the DIY device to analyse on realistic object. Specifically outdoor - print ads of Zubr brewery with evaluation.

There are two different types of platforms in the world of business intelligence - commercial and open source. The main objective of this thesis is to compare two representatives of both worlds - IBM Cognos BI version 10 and Pentaho BI Suite 4.1. This thesis is focused on the theoretical comparison of platforms according to defined benchmarks. Practical application of both platforms is described on example of model company MATASTAV. In the introduction the main topic, objectives and benefits are defined. Then it is necessary to describe expressions that may occur on following pages. The initial situation is defined by example of company MATASTAV. Both platforms are introduced in the next part and then are defined benchmarks with selected method of comparison. Platforms are theoretically and practically compared on following parts of this thesis. Conclusion contains results from both comparisons. Major benefit of this thesis is based on the practical comparison of both platforms on the example company MATASTAV and gathering of personal experiences and problems solved.
